(a) Distribution of the FLT (ns) measured for each slide. Patients were categorised according to stage of treatment. The control group contains slides from patient with inflammatory disease. (b) Distribution of the fluorescence lifetime (ns) in each source group. (c) Hierarchical clustering (average, 1-correlation) for each source group of patients. (Patient numbers and groups are keyed to Tables 1 and 2 respectively). An image of a cell produced by the FLIM system (d) from a group B patient with a FLT of 4.8 ± 0.43 ns, and (e) from a group C patient with a FLT of 1.17 ± 0.3 ns.
